Title: Improvements in or relating to mechanisms for producing a step-by-step linear drive
Inventor: GAITE HAROLD DODIMEAD
IPC: F16H27/02
Filed: 1951-12-31
Abstract: 714,354. Kinematograph apparatus. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd. Dec. 19, 1952 [Dec. 31, 1951], No. 30411/51. Class 97(1) [Also in Groups VII and XL(b)] A step-by-step linear drive mechanism for kinematograph apparatus for causing one end of a drive member to carry out a substantially rectangular movement in response to the reciprocating movement of an actuating member, is arranged so that after the initial movement provided by the actuating member, a plurality of succeeding movements are effected by spring action as mechanical constraining means are successively rendered ineffective due to the preceding movement of the drive member. As shown, the actuation of the spring-biased armature 19 of the electromagnet 20 moves the drive member 10 upwardly by means of an arm 16 engaging the under surface of the head of the member 10, and by rocking a lever 17 tensions a spring 29 so that the head of the member 10 is moved to the right when a shoulder 34 moves clear of the end of a spring-biased pawl 31. When the member 10 is moved clear of the top (engaging) surface of the arm 16, Fig. 3 (not shown), the spring 26, which was also tensioned by the upward movement, moves the member 10 downward to the position, shown in Fig. 4, in which the mechanism remains until the magnet 20 is deenergized when the downward movement of the arm 16 by the movement of the armature 19 allows the head 10 to move to the left under the action of a surface 35 on an extension of the lever 17. The 'pawl 31 re-engages with the shoulder 34 under the action of the leaf spring 33. In the application to driven perforated tapes, pins 36 engage feed-holes in the tape to effect the stepping movement, and retaining pins 37 on a vertically reciprocable member are arranged to engage the tape when the feed pins 36 do not, and vice versa.

Title: Improved manually operated propelling means for toy vehicles and boats
IPC: B62M1/14
Filed: 1934-10-24
Abstract: 426,310. Manual actuation of screw propellers. ETABLISSEMENTS VIMEUXS a.r.l., 140, Rue du Landy, St.-Ouen, Seine, France. Oct. 24, 1934, Nos. 30481 and 30482. Convention dates, June 12 and Sept. 15. [Class 114] [See also Group XXXI] A manually propelled toy vehicle or boat is characterized by the hand levers 21 being pivoted close to the longitudinal centre line of the vehicle or boat. As shown in Fig. 2, the levers 21 are secured to vertical shafts 16, having cranks in vertical alignment with the levers 21 to which connecting rods 22 are pivoted by universal joints 23, the rods being connected by universal joints 24 to crank arms 25 on a crossshaft 26 which carries a sprocket 28 coupled to a sprocket on the rear axle 4 by a chain 30. This device is modified for propelling a boat, by providing, on the shaft 4, a bevel gear which gears with a bevel on the propeller shaft. The propeller shaft carries a fly-wheel. In Fig. 3, the levers 21 actuate shafts 16 having free-wheel pinions 21a, 21<1>a, at the lower ends. The pinion 21a meshes with a wheel 45 rigid with a bevel wheel 46, whilst the other pinion 21a is geared to the wheel 45 through an idler 45a. The bevel 46 gears with a bevel 32 on the propeller shaft 33 which carries a flywheel 35. In Fig. 7, bevels 16a on the shafts 16 drive a double bevel 39 integral with the sprocket wheel 28. The connections between the shafts 16 and the bevels 16a may be freewheels, or, the shafts 16 may be connected to the bevels 16a by cranks and connecting rods.

Polytetrafluoroethylene is placed in a mould 1, a rubber or p.v.c. core 8 is placed on the material, the space around the core is filled with p.t.f.e., and the core expanded by longitudinal pressure to mould the p.t.f.e. As shown in Fig. 1, pressure is first applied to the ram 6 until its surface becomes co-planar with the annular surface of the mould closure 5. Pressure is then applied with the ram 3. In a modification, the bottom of the mould may be closed and after the upper ram has moved the core from the top mould closure the mould is moved upwards to slide over the top mould closure. In a further modification, a core is located in a hole in a bottom mould closure, the mould is filled with p.t.f.e., a top mould closure secured to the mould, and the pressure is applied by a ram which acts through the hole in the bottom mould closure on the ram.

IPC: H01H73/44
Filed: 1921-11-21
Abstract: 191,560. M³ller, F. Nov. 21, 1921. No Patent granted (Sealing fee not paid). Automatic circuitbreakers to take the place of screw-plug fuses and made up in the same form, comprise a screw-plug casing with threaded plug contact c and central contact d and a spring-controlled rotary contact drum v carrying a radial contact p, Fig. 7, in engagement with a spring plate contact q. The circuit through the plug passes from the central contact d through an electromagnet f having poles r and through the contacts p, q to the plug contact c. When an excess current passes through the cut-out, the pole-pieces attract the catch t mounted on the spring arm s and remove it from locking engagement with the hook u on the contact drum v. Consequently the drum revolves in the direction of the arrow, withdrawing the radial contact from engagement with the spring contact. At the same time a screw-head 4 on the part y of the button engages a forked portion 2 of the spring contact and pushes it aside, as shown in Fig. 4. To re-set the cut-out, the guided spring-pressed button 1 is depressed to engage the pin x and rotate the drum into the locked position. The circuit is not made, however, until the pressbutton is allowed to return to release the extension 2 and allow the spring contact to engage the drum in the position shown in Fig. 1.

Abstract: 484,812. Shaping soles. BRITISH UNITED SHOE MACHINERY CO., Ltd., HEATHER, C. H., and BAGSHAW, C. M. Nov. 14, 1936, No. 31148. [Class 17 (i)] A blank sole is subjected to the action of a warm humid atmosphere until the surface is humid but the mid portion of its thickness still dry, and is then immediately subjected to a shaping operation. The latter operation may be sole blank shaping by a machine of the kind described in Specification 400,930, or shaping in a sole laying press of the kind described in Specification 408,953. As described, a number of sole blanks are carried by a conveyer moved one step at each operation of the shaping machine, the conveyer being enclosed in a casing to which hot water vapour is supplied. A sole blank shaping machine has a plunger 35 which reciprocates once during each machine cycle, actuating a bell-crank lever 23 linked to a pawl 25 actuating a ratchet wheel driving a conveyer one link for each cycle. The conveyer chain has thirtyfour links 11 connected by cross-bars, each cross-bar carrying three bars 17 having members 19 at their ends, the bars 17 and members 19 forming, along the upper and lower runs of the conveyer, cages for the reception of sole blanks S. The conveyer is contained in a casing having a lower open end adjacent the operator's position. As the links pass over the forward sprocket wheels, the bars 17 open to allow new sole blanks to be positioned for treatment, fingers 41 arranged at the sides of the conveyer and between the bars removing a sole from each row of bars as they advance. The treated blank drops on to bars 45 convenient to the operator's position. A water reservoir 53 supplies water to a tank 51 containing electric immersion heaters 57. Baffle plates 60 direct the vapour to the casing 1. A handle 38 admits of the chambers of the conveyer being loaded with soles when starting work after an interval. In a modification, the treating chamber is substituted by a pair of chambers 67, one for each operating head of the twin shaping machine, sole blanks being supported on radial bars carried by rings 83 and covered by a plate 79 except for one opening for the change of work-pieces. The rings are advanced half a step at each operation by a link 97. The preferred temperature of treatment is from 110 to 140‹ F. and the approximate time during which the sole is exposed to the vapour is 3 minutes. According to the Provisional Specification, an additional heater is located above water level.
